...and other rarities

In the United States, Nintendo Entertainment System collectors often drool over two carts. Those carts, some colored gray and some gold, contain the three-part competition gameplay used during the 1990 Nintendo World Championships (NWC). The gray NWC carts are believed to potentially exist in the several hundreds, having been given out to winning gamers at competitions around the country. The gray carts were actually used during competition. The more rare gold NWC carts were given to gamers through a raffle in Nintendo Power magazine. The gold carts, though exactly like the gray carts, except in color and label design, number around 50.

Prior to the Nintendo World Championships, however, Nintendo already had held similar competitions in Japan.
